项目摘要
The project addresses challenges of next generation 6G wireless communication systems. For these systems, millimeter-wave (mmWave) and terahertz (THz) frequency bands that support wide bandwidth transmissions will play an important role in providing the advanced services envisioned of next generation systems. Due to the small wavelength, a key enabling technology for reliable and high data rate communication is the deployment of massive Multiple Input Multiple Output (MIMO) systems which consist of a very large number of antennas for transmission and reception. This allows for dense spatial sampling and use of spatial degrees of freedom for effective communication system design. However, the small form factor makes traditional radio-frequency (RF) circuitry design impractical due to circuit complexity, increased cost, and power consumption. These constraints lead to nonlinearities that call for developing nontraditional processing algorithms for which recently developed machine learning networks are suitable. Another challenge is the wireless channel which at these higher frequencies has significant path loss and varies in nature across different frequencies in the bands. To deal with the higher path loss there is a need for finding ways to enhance the quality of the channel, to which this project applies advanced channel morphing methods. The theoretical ideas resulting from the work will be supported with appropriate experimental work to lead to practically viable systems. The project will lead to state-of-the-art wireless communication systems that should help with maintaining leadership in wireless technology as well to train the next generation of researchers in this area of strategic importance.To develop next generation mmWave and THz based massive multiple input multiple-output (MIMO) wireless communication systems using machine learning (ML) algorithms, this project has four major components. One is ML-based sparse channel modeling in severely constrained environments, i.e., limited sensing, limited number of measurements, limited precision, and system imperfections. This work combines domain knowledge with data driven techniques to deal with the nonlinearities and imperfections in the system. A second component is novel channel modeling using block-sparse techniques and development of associated model-based and ML-based inference algorithms. Block channel structure is not analytically tractable in two dimensions and calls for ML techniques to learn from data. A third component is incorporation of reconfigurable intelligent surfaces (RISs) for channel morphing to improve channel quality. A final component of this project is experimental work, channel sounding and ray tracing, to support, validate, and refine the theoretical models.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
该项目旨在应对下一代6G无线通信系统的挑战。对于这些系统,支持宽带传输的毫米波(mmWave)和太赫兹(THz)频带将在提供下一代系统所设想的高级服务方面发挥重要作用。 由于波长小,用于可靠和高数据速率通信的关键使能技术是大规模多输入多输出(MIMO)系统的部署,所述MIMO系统由用于发送和接收的非常大量的天线组成。这允许密集的空间采样和使用空间自由度来进行有效的通信系统设计。然而,由于电路复杂性、增加的成本和功耗,小形状因子使得传统的射频(RF)电路设计不切实际。这些约束导致非线性,需要开发非传统的处理算法,最近开发的机器学习网络适用于这些算法。另一个挑战是无线信道,其在这些较高频率处具有显著的路径损耗,并且在频带中的不同频率上性质不同。为了处理更高的路径损耗,需要找到提高信道质量的方法,本项目应用了先进的信道变形方法。 从工作中产生的理论思想将得到适当的实验工作的支持,以导致实际可行的系统。该项目将开发出最先进的无线通信系统,有助于保持无线技术的领先地位,并培养这一具有战略重要性的领域的下一代研究人员。为了利用机器学习(ML)算法开发下一代基于毫米波和太赫兹的大规模多输入多输出(MIMO)无线通信系统,该项目有四个主要组成部分。一种是在严重约束环境中基于ML的稀疏信道建模,即,有限的感测、有限的测量次数、有限的精度和系统缺陷。这项工作结合了领域知识和数据驱动技术,以处理系统中的非线性和不完善之处。第二个组成部分是新的信道建模使用块稀疏技术和相关的基于模型和ML的推理算法的发展。块通道结构在二维中是不可分析的,需要ML技术来从数据中学习。第三个组成部分是结合可重构智能表面(RIS)的信道变形,以提高信道质量。 该项目的最后一个组成部分是实验工作,通道探测和射线追踪,以支持,验证和完善的理论模型。该奖项反映了NSF的法定使命,并已被认为是值得通过使用基金会的智力价值和更广泛的影响审查标准进行评估的支持。
